Title: Automatic switching control of vehicle headlamps - involves light intensity detector, switching and control ccts.
IPC: B60Q1/14
Filed: 1973-01-15
Abstract: Automatic switching control of vehicle headlamps involves a relay contact which is interposed between the headlamps and the current supply source. The winding of the relay is connected to a control module. The input nof the module is connected to a light intensity detector, which switch the control module from a non-active to an active state or vice versa. The lamps are automatically switched on when the ambient light intensity falls below a given value, and they are automatically switched off when the ambient light intensity exceeds a given value.

Title: Electromagnetic filter for high temp. and pressures - using a spherical filter medium magnetised by a coil
IPC: B03C1/025
Filed: 1973-05-23
Abstract: A filter for removal of magnetic particles of a few microns dia. from a flowing fluid employs a filter medium of ferromagnetic spheres, or similar, which are magnetised by a coil. Retention of particles without power to the coil can be prevented by destroying the remanent properties of the medium with a second coil. Used for high pressure (above 2000 p.s.i.) and high temp. (above 650 degrees F) applications involving removal of small particles of ferromagnetic material from a fluid. Construction permits forced cooling for high temp. use, and may be adapted for very high pressures.

The waist of each catching element cooperates with the waist of the next adjacent element to secure the stem of the next adjacent element to secure the stem of a plant. There are tow rows of figure of eight elements arranged one above the other. A pair of guides leads each stem onto a knife and the severed plant is carried by the catchers to the rear of the elevator where it is discharge onto a storage pallet as the figure of eight elements become spaced apart as they pass around the rear hub of the elevator. The figure of eight elements may be of plastic or spring steel.
Patent FR-2225831-A1 (FR)
Title: Colour selective electrodes for picture tubes - in two-stage etching process used for making shadow masks
IPC: H01J9/14
Filed: 1974-01-30
Abstract: The process produces small holes for exposure of the luminescent screen, after which the holes are enlarged by further etching (after etching). The electrode plate is first coated with photolacquer and exposed using a mask of suitable pattern, then developed to remove the exposed areas. Etching in FeCl3 is used to produce small holes and the bores are coated with Cu or Ni by electroless- or electroplating, after which the photolacquer is removed. A coating resistant to FeCl3 (e.g. Fe3O4 or iron phosphate) is then applied to the electrode except in the holes. The mask so obtd. is used to expose a light-sensitive layer on a glass plate so that a luminescent screen is produced, after which the electrode is etched a second time in FeCl3 to remove the plating and enlarge the holes to the required size. The etch-resistant coating is then removed and the entire electrode, including the holes is coated with a matl. Which both protects against rust and suppresses sec. electron emission; this coating is essentially carbon.

Title: Cast resin seals for heat exchanger tube joints - comprising PVC or epoxy seals about each tube end
IPC: F28F9/16
Filed: 1976-03-05
Abstract: The joints between manifold tanks and arrays of tubes of a heat exchanger are sealed by applying a sealant locally around the end(s) of each tube. A pref. sealant comprises PVC deposited from a simple plastisol and subsequently gelled to a tough, elastic seal by thermal shock treatment at 140-200, pref. 160 degrees C. Alternative sealant is made by mixing epoxy resin reagents and curing them in situ to an elastic sealant. The process is esp. suitable for making air cooled water radiators for automobiles etc. Individual seals are more tolerant of dimensional or alignment variations than prefabricated multi orifice seats or gaskets, and require less sealant material.
Patent FR-2346039-A1 (FR)
Title: Engine exhaust gas purifier - has swirl generator for encouraging extinction of sparks and sepn. of particles
IPC: F01N3/06
Filed: 1976-03-31
Abstract: An engine exhaust gas purifier includes a cylindrical casing with coaxial inlet and outlet fittings projecting through end plates of the casing, the inlet fitting terminating within a swirl generator located in the casing while the outlet fitting terminates adjacent a larger-dia. coaxial guide tube projecting through an annular partition which is located in the casing in spaced relation to the downstream end plate and which includes a port bypassing the guide tube. In use, gases entering the swirl generator are constrained to flow outwards between swirl-inducing vanes and then flow in a helical pattern along the casing so that particles entrained in the gases migrate towards the interior surface of the casing and pass through the port to accumulate in an annular space around the inner end of the outlet fitting where any remaining sparks are finally extinguished and particles are abraded before becoming re-entrained in the bulk of the gases which pass through the guide tube into the outlet fitting.

Patent FR-2326184-A1 (FR)
IPC: C07D307/24
Filed: 1976-09-16
Abstract: Prostaglandin analogues of the formula in which the substituents are defined in Claim 1, are prepared by selective oxidation of the OH group in corresponding PGF alpha or PGF beta compounds, resulting in the corresponding 11-oxo compounds. This compound is then isomerised to form 13,14-dihydro-12,13(E)-didehydro-PGD or 13,14-dihydro-12,13(E)-didehydro-9-PGD compounds and subsequently dehydrated. Another process is based on direct dehydration of the reaction product from stage 1. The resulting compounds can be used for the same purpose as known prostaglandins.

Title: Treatment of effluent, esp. contg. acid, alkali, metal and/or cyanide - by simultaneous redox reaction
IPC: C02F9/00
Filed: 1976-11-12
Abstract: The acid effluents and metallic solutions are placed in a first container, teh metallic solutions contg. hexavalent Cr in a second, and the alkalies and cyanides in a third. A quantity of alkaline effluents and reducing agents is withdrawn and introduced into a container which also receives the right quantity of acid effluents + oxidising agents to ensure careful control of the chemical neutrality of the mixt. The air contained in the receiver of the mixt. is mixed with the gas liberated from the mixt. After sufficient time for the hexavalent Cr to be reduced in contact with the cyanides, the HCN gas is destroyed by contact with an oxygen-contg. product. After verification of its disappearance, the mixt. is evacuated without danger to a means of separating the liquid and the decantable products. The method is partic. useful for effluents from surface treatment and galvanoplastic mfg.
